Application The .numeral 10 indicates a farm tractor wluch may bepreferably of any of the small types of ;tractors,and is provided with arear axle 11 and a front axle'12. The axle- 11 isprovided with tractorwheels 13 while the axle 12 is provided with wheels 14. The tractorisalso provided with a belt wheel 15, which is driven-by mechanism notshown 01 described as this forms no partof my present invention.

My improved device comprises frame members 16, one of'which is laced ateach side of the body portion of t e tractor and above said axles andinside of the wheels,

the rear end of each of said members 16 being provided with U-bolts 17designed to rest in a detachable sleeve member 18 se-' This 'U-bolt isso Y cured to the axle 11. mounted that the free end of the lever 16 maybe raised or lowered as hereinafter to be described.

The members 16 are parallel and extend beyond the front axle 12, eachbeing provided with a ,downwardl and forwardly extending portion 19 whicterminates in a forwardly extending portion 20, which is again providedwith a downwardly extending portion 21, the saidportion 21 having a.

forwardly extending. end member'22. Pivot bars 23, preferably tapered,are' rigidly secured to the bottom of a scoop 24 which is open at itsfront and top. The portions 22 andthe pivot bars 23 are formed withbearin openings in registration and are ivota1 y connected by pivot pins23 whic rest substantially beneath the center of gravity of the scoopwhen it is filled. A back 25 of the scoop is designedto rest adjacent toand slightly ahead of the members 21, as clearly shown in Figures 2 and3.-

The scoop 24 should be set as close to the front axle as is practical inorderto give ear casing 26 means of bolts 28. The shape of this" Ill!bracket 27 will have to be different on difierent makes of tractors sothat it -may be adapted to be connectedj to. bol ts' tha;,t are alreadyin the tractor frame. Rotatively members are rigidly secured to theshaft.

The inner head l'nember of thedrum-32fis' provided withratchetteeth"33-'whiclf are" .des igl lcdtobe engaged bya' pawl Mme-untedin' a be'aring"35' extended from the vbearniediately aboveflthebelt wheel 15, the'two pawl 34 is provided with a handle 36 for thepurpose of releasing said pawl' fr'lomfs'aid ratchet when it isso-rdesfired. The; belt jwheel '30 is mounted imsaid wheels",being'operatively connected by eans (hfi -t} "belt 37', the said wheels beingformed {with grooves for thepurpose of receiving said belt so that thesaid belt may be run 1oosely"whenthe'machinje is not.in

operation without'comingofi." I ,7 p v Adjacent to one sidefo'f the belt37, I have provided 'a belt ghtener' wheel 38' mounted on ,t'he'l'ever39a'ndpivoted at 40. The lever I 39 is provided with janju pwardlyextending hand leveri 4'1 so ."arranged that as the said lever 41 ismoved rearwardly,"'the belt 37 will be tightened andthe wheel rotated Ithrough the driver 15.',.

7 Secured to the forward frame'of the tractor adjacent? to the: forwardend'of the en gihe, 'Iih'a've 'rov'ided a beari "42, 'which may besecure in position bolts 43. This bearing is designed to receiveatransverse rocksha'ftM, each end of the shaft 44 beingprovided-"within. lever 45' having an upwarjdly xtendin'g arm 46 and a-down'ward extendirh'lflt arm '47. Each ofthe arms 47 is V proyidd atvits lower end with a pivoted link 481which is extended forwardly to apoint substantially verticallyabovethe pivot centers of" the members 22and 23, and a slight dista nceiabovethe' scoop 24.

The fre'e en s of the members 48 are pro-' vided with a'transverselyarranged shaft t9 which is'of a len'gth slightly greater than the widthofthe iscoopl' "Each end of said shaft 49 is providedfwith a downwardlyextending link 50., the lower end of each of which is pivotally'connectedto an adjacent sidemember of 'the scoop '24 by means of a pivot51'which islocated slightly above and back of the pivot of the members22 and 23. as clearly shown in Figure 1'.

The upper ends of the arms '46 are pro vid'ed with a transverselyarranged shaft 52, each end of which is provided Wltll a pivoted link53. the lower end of each of said links being pivotally mounted to theshaft 49, as

clearly shown in Figures 1 and 2. The shaft 52 isprovided with a set ofsheaves 53 near each end inside of the'arms 46. Secured'to each of theforwardly extending members of the bracket 27,; I have provided a sheave54' substantially in line with'the sheaves 53. Rigidly secured to thebracket member for the sheave54, I have provided oneyendof-a rope 55.This rope is designed to pass under "'0- one of the sheaves 53 andreturned to the sheave 54,"thence' back to the second sheave 53, and hasits other end mounted on a drum 32 inj'such a mannerthat as the drum 32is operated, the shaft 52 will be drawn toward said drum, whichin turnwill cause the lower end of the members 47 to be advancedtogether withthe link 48. Theshaft 49 will be elevated'due to the link connections53?. This as will hereinafter be more fully set forth. It will be seentliat'on account of thepo'sb tion of the-"pivot 51 relative to thepivo'tof the members 22 and 23, that the scoop 24 would be dumped by theelevating movement just described. 1 u 4 For locking the scoop in itsnormal position,'I have provided hooks 56 which are designed to'engag'ethe upper edge of the mem her 25, and'having'thelr lower'ends pivotallyconnected to the inside of the members 20 andj21i These hooks are heldagainst a for ward movement by means of pins 57 engaging .a downwardlyiprojecting lug 58 from said hooks, best shown in Figures 3 and 4. Forreleasing the hooks, I have provided a shaft 59 pivotally mounted on theback side ofthe plate 25 'by brackets 60, and in front. Offthe books 56.Secured to the shaft 59 beneath'each of the'ho oks 56, I have provideda'cam61so arranged that when "in one position'of its..movement, thehooks will be permitted to engage the top edge of the plate 25, and whenin anotherposition of its movement, the hooks will-be forced backward towhile the other rests against the plate 25.

The movement of said "cam is limited in one directionb y means of a pin63- carriedby the'shaft59 and which engages the said plate 25.

provided a hook shaped cam 64'designed tobe engaged by a book 65. oneend of which is pivotally connected to a lever 66, which is in turnpivoted to the member 20. The upper endofth lever 66 is provided with arod 67 which extends rearwardly and is operativelycon'rrected to a handoperated lever 68. Thus it will be'seen that as the hand lever 68 ismoved] rearwardly, the hook 65 will be moved rearwardly through thelever '66, which will cause th'e'hooksh'apedcam 641:0 be rotatedandwithit the-shaft 59. This in turn will cause the cam61 tobe rotatedagainst the action; of the spring 62, and the hooks 56 released'fro'mjth'e upper edge of the Secured to one end of the shaft 59,1have 5 I plate 25. When the hooks 56 have been released from the upperedge of the plate 25, the scoop will assume a vertical positionsubstantially as shown by dottedlines in Figures 1 and 3.

To return the scoop to its normal position,

I have provided a link 69 which is pivoted to one of the side plates ofthe scoop- 24 near its bottom and back edge. The upper end of the link69 is provided with a slot 70 which .is designed to receive a pin 71projecting laterally from one side of the hook member 65. When the scoophas assumed the position shown in dotted lines in Figure 3, the link 69and the hook 65 will assume a position in alinement in' such a mannerthat the lever 68 ma be moved rearwardly, which will cause t a scoop tobe returned to its normal position. The slot 70 permits the pin 71'tomove slightly therein so that the hook 65 may engage the hook 64. v

By this arrangement, it will be seen that a. single lever 68 may 'be'employed to both unlock the scoop and return itto its normal position ofmovement.

, The practical operation of my device is substantially as follows: 7

Assuming that the mechanism above described has been mounted on thetractor and that the scoop is in the position shown in Figure 1, and.that it is desired to fill the scoop, the operator will advance thescoop into the material by manipulating the gear mechanism for drivingthe 'tractor wheels 13. After the scoop has been filled, the ban-- 'dle41 is grasped and, moved r'earwardly and the scoop 24 to be elevated toa position shown in dotted lines in Figure 1. The pawl 34 of the ratchet33 will then hold the load 'in its elevated position.

The tractor'may then be driven together with a load to any desiredpoint, such for instance as a fill for bridge abutments or the like. Thescoop maybe moved to a position over the edge of the bank, after whichthe lever 68 will be moved rearwardly causing the ca1ns61-toforcethe'hooks 56 out of engagement with the top edge of the plate 25.'

In this connection, it will be noted-that the load is supended by meansof the pivots 51, and when the load is in. the position shown in dottedlines in Figure 1, the center of gravity will be slightly back of thesaid pivot center. This will permit the hooks 56 to be'easily disengagedfrom the top edge of the plate 25, but the weight of the members -16, 20and 22 is suspended from the pivotal point slightly aheadoft-he pivot51, which is sufficient to change the center of gravity of the load tothe forward side of .the pivot 51, which is, of course,the true centerof v gravity, and'the scoop will be dumped.

After the said scoop has been dumped, the lever 68 is again grasped andpulled rearwardly which will cause the scoop'to assume its normalposition as before described. I am aware of the fact that other scoopmechanisms have been pivotally mounted to tractors, but the arm memberswhich take the placeof the arm. 16 of my device are pivoted at a pointnear the'forward end of the tractor in. such a manner that as the scoopis elevated, the scoo will'be thrown ahead or to a greateroverhanging-position. This makes it impossible with a tractor 'of thelight farm type to use a scoop of sufiicient size to be practicah'due tothe fact that the weight in the scoop will elevate'the rear axle of thetractor dueto the excessive overthe member 16- are on the rear axle, thesaid arm l6 being of such a length that as the scoop is elevated, itmoves in substantially.

a vertical plane with a slight forward movement.

ward end of the tractor and at a point considerably above the shaft 49,I have provided means through the frame construction con- By mountingthe shaft 44 near the forsisting of the arms 46, 48 and 53* which-willcause the shaft 49 to be moved to a point substantially vertically abovethe pivot 51 when the scoop is in its elevated position, as clearlyshown in dotted lines in Figure 1, so that the lifting strain on thescoop is in'substantially a vertical line before the scoop is dumped. Asthe scoop is dumped, the link will assume a slightly inclined positionindicated by the numeral 7 2. This will assist in returning the scoop toits normal positionafter it has been dumped, but the inclination of thelink 53 is not great enough to materially hinder in the dumping. Thus itwill be seen that I .have provided a device for gathering and'deliveringmaterial, of simple, durable and comparatively inexpensive constructionwhich is adapted to be attached to a light farm. tractor, and providedwith a very simple and inexpensive operating device for operating andcontrol ding the scoop.
